The CD made it to about 3/4 of the way through the rough draft before my business tanked last summer.
I lost two customers that represented about 1/3 of may annual income when they went out of business last summer. Shortly after that my wind generator crashed and I had no practical testing system to work with and no money to rebuild it or justify putting toward experiments so it was not a good summer for the AE projects and every thing basically just stopped right there.
I picked up some business last fall and restarted work on the AE stuff for a few weeks until my mom died. Unfortunately I had to deal with all the stuff that relates to someone dieing unexpectedly which used up any time and motivations I had to continue on with the AE work as winter set in. Plus once the snow piles up around here all the wind generator work gets put on hold simply due to not being able to get around in the deep snow.
It just ended up being a very bad year for this type of work all around and everyone here who has been patiently waiting didn't get what they have been waiting for once again.
As you may have seen in the **** chat area I did get my wind generator up and going again a little while back,
https://www.electro-tech-online.com/threads/wind-generator-up-again.104543/ , so I have been working on a new multistage GTI design that will run in the 2-3 KW range.
The working range for this one will be for a roughly 25 - 180 volt input split over three stages. 25 - 50, 50 - 100, and 100 - 180 volts.
I ordered parts for it this week and did have plans to use it for a 'Grid Tie Inverter Schematic 2.0' thread but I just got offered a truck driving job,
https://www.electro-tech-online.com/threads/going-back-to-work.105194/ , that is too good to turn down so I likely will not have time to work with much of this stuff for a long time now.
I had hoped to have more time this spring to work on finishing much of this GTI stuff but the weather warmed up about 6 weeks early unlike last year where it was 6 weeks later that normal. Around here when its warm enough to work I tend to go and leave the hobby stuff behind until later.
Sorry for the delays and inconveniences but thats sort of how life goes.
I am still working on this stuff but I have no idea of when I will get much of it done. After all most of this is basically just a hobby for me after all so its always been on the low priority list for being worked on right from the beginning.
Thanks for the offer to pay but I do all of this for free so I can work on it at my pace and as my time permits. In the long run more people will benefit from it that way.
Sorry for the continuing delays but at least now you know why.
But just for a little tease here is a picture of the new version of the 20+ Kw direct connection GTI partially assembled. At least I got some of the big GTI worked on for part of last summer.
